To provide a display panel with a structure that prevents moisture permeation through an opening.SOLUTION: A display panel of the present invention comprises: a substrate that has an opening; a plurality of light-emitting diodes that are arranged in a display area surrounding the opening; a plurality of sealing layers on the light-emitting diodes that include a first inorganic sealing layer, an organic sealing layer on the first inorganic sealing layer, and a second inorganic sealing layer on the organic sealing layer; and a multilayer film that is arranged between the opening and the display area. The multilayer film includes a first layer and a second layer on the first layer. The second layer has a leading end part that projects in a horizontal direction parallel to a top face of the substrate beyond a point where a side face of the first layer and a bottom face of the second layer are in contact with each other. The length of the leading end part is larger than 0 μm and less than 2 μm and is the distance between the point and a side face of the leading end part.SELECTED DRAWING: Figure 10 【課題】開口を介する透湿を防止する構造の表示パネルを提供する。【解決手段】本発明の表示パネルは、開口を有する基板と、開口を取り囲む表示領域に配置された複数の発光ダイオードと、第１無機封止層、第１無機封止層上の有機封止層、及び有機封止層上の第２無機封止層を含む、複数の発光ダイオード上の封止層と、開口と表示領域との間に配置された多層膜と、を備え、多層膜は、第１層及び第１層上の第２層を含み、第２層は、第１層の側面と第２層の底面とが接する地点を越えて基板の上面に平行な水平方向に突出する先端部を有し、先端部の長さは、０μｍよりも大きく２μｍ未満であり、地点と先端部の側面との間の距離である。【選択図】図１０
